Method: Preparation of Lymphocyte Cell Pellet for Storage - http://humgen.wustl.edu/hdk_lab_manual/hcc/hcc5.html

Category: Cell Biology and Cell Culture: Cell Culture Techniques: Cell Line Preservation Freezing

Following propagation to 1 X 108 cells, lymphoblastoid cells are conveniently stored at -80 degrees C to preserve the high molecular weight DNA in the cells until the DNA is purified. This procedure describes the steps required to harvest and freeze the c - [Read Method: Preparation of Lymphocyte Cell Pellet for Storage]

Protein Precipitation Microplate - http://www.htslabs.com/HTML/Wellplates/Applications/protein_precipitation_microplate.htm

Category: Protein Protocols: Protein Precipitation Procols

Laboratory sample cleanup is a necessary part for analytical preparation analysis. The removal of Contaminants such as proteins, cell debris and other materials is an important step. Typically this has been done by using Acetonitrile and then Centrifugation to pellet the debris leaving the clean supernant. After this process supernatant can be used for further analysis by HPLC, GC, MS and other analysis tandem methods. HTS Labs. - [Read Protein Precipitation Microplate]

Purification of Golgi Membranes from a Light Mitochondrial Fraction in a Self-Generated Gradient - http://www.axis-shield.com/densityhome/optiprep/S12.pdf

Category: Cell Organelle Protocols: Subcellular Fractionation Protocols: Membrane Isolation Protocols

This protocol uses a "light mitochondrial" pellet from a mammalian liver homogenate. The gradient thus has to resolve a variety of denser components (peroxisomes, lysosomes, mitochondria) from the Golgi membranes, which have a low density in iodixanol (1.06-1.09 g/ml) [1]. The protocol is specifically tailored to the purification of Golgi membranes from this pellet and is unsuitable for the isolation or analysis of other organelles present in the light mitochondrial fraction. - [Read Purification of Golgi Membranes from a Light Mitochondrial Fraction in a Self-Generated Gradient]

Preparing Stock Plating of Bacteria Protocol

A protocol for the preparation of stock plating of bacteria.

Lambda Phage Protocol Large DNA Preparation

Single Stranded Plasmid DNA Isolation Protocol

A Single Stranded Plasmid DNA Isolation Protocol describing the production and isolation of single-stranded DNA (ssDNA) using bacteriophagemid-containing bacteria and helper phage. Infection of the host cells with helper phage allows for packaging of ssDNA into bacteriophage. The ssDNA can then be isolated from phage particles.

Tubulin Polymerization Protocol using GTP and GMPCPP

Tubulin is polymerized into microtubules by incubating tubulin at 37°C with GTP. A nucleation seed is added when the purpose is to assay microtubule elongation. Tubulin can also be polymerized for the purposes of recycling the tubulin or labeling the microtubules with fluorescently labeled tubulin. Based on the protocol by Timothy Mitchison of Harvard University.

Acid Guanidinium Thiocyanate RNA Isolation Phenol Chloroform Extraction

A single step RNA isolation protocol using Phenol Chloroform Extraction and Acid Guanidinium Thiocyanate. This RNA isolation method uses the fact that guanidinium thiocyanate can simultaneously lyse the cells and inactive cellular RNAses during the initial RNA isolation step allow a single step in the method.

In Vitro Translated Xenopus Mos Kinase Assay Protocol

In Vitro Translated Xenopus Mos Kinase Assay Protocol. In response to progesterone, immature Xenopus oocytes mature to eggs that can be fertilized. The Mos protein kinase is essential for oocyte maturation, most likely due to its ability to activate the MAP kinase cascade. This MAP kinase cascade eventually leads to the activation of Cdc2/cyclin B and entry into M phase. In this protocol, tagged Mos kinase is translated in vitro, immunopurified, and used in a kinase assay.

Antibodies Phage Expression Protocol Using 96-well Microtiter Plates

A Phage display expression protocol for antibody expression in 96-well microtiter plates.

Immobilized Antigen Phage Antibody Selection Protocol

A protocol for the selection of Phage Antibodies using Immobilized Antigen. This method describes the selection of antibodies from bacteriophage antibody libraries that recognize a specific antigen. The phage display library of antibody-displaying phage particles is exposed to antigen attached to a solid substrate (Nunc Immuno™ tubes). The phage particles with affinity for antigen bind to the immobilized antigen and are selected from the library of phage expressing antibodies.

Histone H1 Kinase Activity Assay

Histone H1 Kinase Activity Assay Protocol. This protocol describes assaying kinase activity of a putative kinase using Histone H1 as the substrate. Histone H1 is the canonical kinase substrate in this type of assay. Phosphorylation of Histone H1 is assessed by SDS-Polyacrylamide gel electrophoresis followed by autoradiography.
